Aliens & Mega Disasters - S4E4

Have ancient aliens been responsible for joy-gantic mega disasters like Volcanoes, Earthquakes, Tsunamis, and Climate Change? Or were they simply trying to warn us against these disasters? Is it something far more sinister? Like advanced flesh and bolts Extra Terrestrials trying to "cull" the human "herd" as it were? Steve and Joey don't really know, because our plucky ancient astronaut theorists do a pretty questionable job of providing evidence. But hey, that's why we love 'em so darn much! Let's prooooooooooooobe into mega disasters and see if the "gods" were really messing with our climate and killing dinosaurs and if Noah was real...n'stuff.
